Authorities are looking for a South Whitehall Township man they say is one of 50 people involved in a massive New York City building inspection bribery scheme.

David Weiszer, identified as an unregistered expediter, was charged with bribing several New York City Department of Building employees, including the chief of development, an inspector and clerks, to get construction approved in the city or get favorable inspections, according to a news release from the Manhattan district attorney's office.

A spokesman with the district attorney's office said Weiszer has not been arrested as of Saturday. He is charged with four counts of bribery in the second degree and one count of bribery in the third degree, all felonies.

Weiszer owns a home in the 1100 block of North Cedar Crest Boulevard, according to Lehigh County records. He has also lived in Allentown, records show.

According to published reports, Weiszer has been on the run for three months since investigators went to his Lehigh Valley home to seize records.

New York City police and the district attorney's office announced last week charges against 50 people involved in the widespread housing fraud and bribery schemes in Manhattan, Brooklyn and Queens. All but Weiszer have been arrested.

The two-year investigation revealed $450,000 worth of alleged bribes between employees with the city's departments of Building and Housing Preservation and Development, and property managers and owners, expediters, contractors and an engineer.

Authorities said Weiszer, who worked for developers, paid off the Building Department's chief of development starting in 2011 to get construction started. According to a news release, Weiszer gave the chief of development and his wife $200,000 for home mortgage payments, two sport utility vehicles, a cruise, and money for airline tickets, home renovations and other personal expenses.

Weiszer also paid $70,000 to an inspector for signing off on inspections, the news release said. In addition, Weiszer allegedly paid two clerks $2,000 to $3,000 at a time for allowing him to cut past people waiting in line at the Department of Building's Brooklyn office without having to show required credentials.

Weiszer also bribed a manager with the city's Small Business Services, authorities said.

Weiszer was previously charged, along with the owner of a Berks County poultry plant, with illegally dumping chicken guts, blood and other parts into the Schuylkill River between May 2006 and January 2008. Weiszer worked as the poultry plant's pre-treatment plant operator. According to court records, charges against him were either withdrawn or dismissed.
